# Session does not start

> A launch refused, or a session stuck on starting or marked failed: what each message means, what you are charged, and what to do next.

A session either is refused at launch, before anything is held, or starts and fails while the machine is prepared. Neither is charged.

## Refused at launch

The launch form shows the reason. The same reason comes back from the API as an [error code](https://nodelodge.com/docs/errors-and-rate-limits).

| Message or code | Fix |
|---|---|
| Add credit, `CREDIT_INSUFFICIENT` | The budget is higher than your available credit. Add credit, or lower the budget. |
| Add a card, `TRUST_LIMIT` | Your account is not verified. Save a card or make a first payment in **Billing**. |
| GPUs at a time or GPU class, `TRUST_LIMIT` | The session goes past your [account limits](https://nodelodge.com/docs/account-limits). Stop a session, pick another GPU, or request a higher limit. |
| Payment failed, `ACCOUNT_BLOCKED` | See [Payment declined](https://nodelodge.com/docs/troubleshooting-payment). |
| Confirm your email, `EMAIL_NOT_VERIFIED` | Open the confirmation link sent to your inbox. |
| Accept the terms, `TERMS_REQUIRED` | Accept the current terms of use in the console. |
| Machine unavailable, `RESOURCE_UNAVAILABLE` or `PARTNER_UNAVAILABLE` | Someone rented it first, or the offer changed. Reload the catalog and pick another. |

## Stuck on starting

**Starting** covers the creation of the machine and its checks. It is free: billing starts when the session is **running**.

- Secure: up to 15 minutes.
- Community: up to 10 minutes.

Past that, the session fails on its own. Wait for it, or select **Stop session** to stop waiting.

## Failed to start

The session page says **The session did not start** and why.

- Nothing is charged.
- The whole budget returns to your credit.
- No receipt is issued.

Launch again. If the same offer fails twice, pick another machine.
